From Ed Bott’s Blog:
I can’t vouch for the accuracy of this resource, but it sure does look comprehensive. Definitely a good starting point if you’re stumped by what one of those obscure BIOS options really means.
Consider this and similar sites as reference tools, not as a bible. For what it’s worth, I don’t recommend spending a lot of time and energy tweaking BIOS settings for better performance. The odds that you’ll screw something up and hose your system are much greater than any minuscule performance gain you’re likely to see. But sometimes you can fix a conflict or provide a better configuration for a specific piece of hardware than the default settings.
As always, Ed’s blog is great! Check out both Ed’s blog, as well as the link he refers to.
